1. Field of the Invention
The present invention relates to marking products and, more particularly, marking outer housing surfaces of electronic devices.
2. Description of the Related Art
Consumer products, such as electronic devices, have been marked with various information for many years. For example, it is common for electronic devices to be marked with a serial number, model number, copyright information and the like. Conventionally, such markings are done with an ink printing or stamping process. Although conventional ink printing and stamping is useful for many situations, such techniques can be inadequate in the case of handheld electronic devices. The small form factor of handheld electronic devices, such as mobile phones, portable media players and Personal Digital Assistants (PDAs), requires that the markings be very small. In order for such small markings to be legible, the markings must be accurately and precisely formed. Unfortunately, however, conventional techniques are not able to offer sufficient accuracy and precision. Thus, there is a need for improved techniques to mark products.
The invention pertains to techniques or processes for providing markings on products. The markings provided on products can be textual and/or graphic. The techniques or processes can provide high resolution markings on surfaces that are flat or curved. In one embodiment, the products have housings and the markings are to be provided on the housings. For example, the housing for a particular product can include an outer housing surface and the markings can be provided on the outer housing surface. The products can, in one embodiment, pertain to electronic devices, such as portable electronic device (e.g., handheld electronic devices).
In one embodiment, a material (e.g., UV ink) can be configured to be specifically sensitive to UV radiation. In one example, the material can be sensitive to the UV radiation such that the material can be partially cured. Then, after being partially cured, the material that has not been partially cured can be cleaned from the surface. Subsequently, the remaining partially-cured material can be completely cured.
In another embodiment, a UV ink can be configured to be specifically sensitive to multiple different wavelengths of UV radiation. In one example, the UV ink can be configured to be sensitive to radiation, such as UV radiation, of a first wavelength and a second wavelength. For example, in a first pass, a UV laser applying UV radiation of a first wavelength can be used to cure selective portions of the UV ink, and then, in a second pass, a laser can apply radiation to ablate away undesired portions of the UV ink.
In still another embodiment, a marking material can be placed on a surface and configured to selected change color under laser control. The marking material, such as ink, can include one or more initiators. For example, the initiators can be dye additives. The one or more initiators in the marking material can serve as color activators. Laser energy can then be selectively applied to initiate colorization of the marking material. Different initiators can be receptive to different wavelength of laser energy such that different colors can be produced using different wavelengths. The colorization can be induced before, during or after cure of the marking material.
In general, markings, or annotations, provided on products according to the invention can be textual and/or graphic. The markings can be provided in one color or multiple colors. The marking of a product can be used to provide the product (e.g., a product's housing) with certain information. The marking can, for example, be use to label the product with various information. When a marking includes text, the text can provide information concerning the product (e.g., electronic device). For example, the text can include one or more of: name of product, trademark or copyright information, design location, assembly location, model number, serial number, license number, agency approvals, standards compliance, electronic codes, memory of device, and the like. When a marking includes a graphic, the graphic can pertain to a logo, a certification mark, standards mark or an approval mark. The markings can be used for advertisements to be provided on products. The markings can also be used for customization (e.g., user customization) of product housings (e.g., customized external appearance via markings).
One aspect of some embodiments provides product markings using an ultra-violet (UV) curable material. Here, a UV curable material can be placed on a product surface, and then selectively cured on the product surface in places where markings, namely text and/or graphics, are to be provided. Subsequently, remaining UV curable material at the product surface that has not been cured can be removed such that the product surface thereafter includes the text and/or graphics for the product marking. The product marking process according to the invention is suitable for use on flat, curved or complex surfaces.
The invention can be implemented in numerous ways, including as a method, system, device, or apparatus. Several embodiments of the invention are discussed below.
As a method for depositing material to selected regions of an electronic device housing, one embodiment can, for example, include at least: depositing a layer of UV curable material onto a housing surface of the electronic device housing; curing select portions of the layer of UV curable material that are desired to remain on the outer surface housing; and removing remaining portions of the layer of UV curable material that have not been cured by said curing.
As a method for depositing material to selected regions of an electronic device housing, another embodiment can, for example, include at least: forming a mask layer having at least one predetermined opening; adhering the mask layer to a housing surface of the electronic device housing; depositing a layer of UV curable material onto the housing surface, the layer of UV curable material being provided on the housing surface at least within the predetermined opening of the mask layer; removing the mask layer from the outer surface housing; curing select portions of the layer of UV curable material that are desired to remain on the outer surface housing; and removing remaining portions of the layer of UV curable material that have not been cured by said curing.
As a method for depositing material to selected regions of an electronic device housing, another embodiment can, for example, include at least: depositing a layer of UV curable material onto a housing surface of the electronic device housing; and directing UV light from a UV laser onto select portions of the layer of UV curable material on the housing surface to thereby cure the select portions of the of the layer of UV curable material that are to remain on the outer surface housing. Optionally, the method can further remove any portions of the layer of UC curable material that have not been cured, and apply a translucent protective layer to the housing surface so as to cover at least the select portions of the layer of UV curable material that have been cured on the housing surface.
As a method for labeling a product, one embodiment can, for example, include at least: depositing a layer of UV curable material onto a surface of the product to be labeled; curing select portions of the layer of UV curable material that are desired to remain on the surface of the product; and removing from the surface of the product remaining portions of the layer of UV curable material that have not been cured by said curing.
As a method for depositing material to selected regions of an electronic device housing, one embodiment can, for example, include at least: depositing a layer of UV curable material onto a housing surface of the electronic device housing; partially curing select portions of the layer of UV curable material that are to remain on the surface housing; removing remaining portions of the layer of UV curable material that have not been partially cured by said partially curing; and completing curing of the select portions of the layer of UV curable material that were previously partially cured.
As a method for depositing material to selected regions of an electronic device housing, one embodiment can, for example, include at least: depositing a layer of UV curable material onto a housing surface of the electronic device housing; curing, using UV radiation of a first wavelength, select portions of the layer of UV curable material that are desired to remain on the surface housing; and removing, using UV radiation of a second wavelength, unselected portions of the layer of UV curable material, the second wavelength being different than the first wavelength.
As a method for depositing material to selected regions of an electronic device housing, one embodiment can, for example, include at least: depositing a layer of curable material onto a housing surface of the electronic device housing; applying a first predetermined wavelength of radiation to one or more desired portions of the curable material that are to be colored to a first color; and applying a second predetermined wavelength of radiation to one or more desired portions of the curable material that are to be colored to a second color.

The invention will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
The invention pertains to techniques or processes for providing markings on products. The markings provided on products can be textual and/or graphic. The techniques or processes can provide high resolution markings on surfaces that are flat or curved. In one embodiment, the products have housings and the markings are to be provided on the housings. For example, the housing for a particular product can include an outer housing surface and the markings can be provided on the outer housing surface.

One aspect of some embodiments provides product markings using an ultra-violet (UV) curable material. Here, a UV curable material can be placed on a product surface, and then selectively cured on the product surface in places where markings, namely text and/or graphics, are to be provided. Subsequently, remaining UV curable material at the product surface that has not been cured can be removed such that the product surface thereafter includes the text and/or graphics for the product marking. The product marking process according to the invention is suitable for use on flat, curved or complex surfaces.
Embodiments of the invention are discussed below with reference to
Initially, the product marking process 100 deposits 102 a layer of ultra-violet (UV) curable material onto a housing surface of a product. In one embodiment, the UV curable material can be adhesive material that can be applied to the outer housing surface as an adhesive layer. The housing surface can be flat or curved. Next, a UV light can be applied 104 to selected portions of the layer of UV curable material that is to remain on the housing surface. Here, the UV light is applied 104 so as to cure the selected portions of the UV curable material. As a result, the selected portions of the UV curable material are cured and thus become firmly adhered to the housing surface. Thereafter, the unselected portions of the layer of UV curable material can be removed 106 from the housing surface. Since the unselected portions of the UV curable material have not been cured, such unselected portions have not firmly adhered to the housing surface. As a result, through use of a fluid (e.g., water, solution, dissolvent), the unselected portions of the UV curable material can be removed from the housing surface, while the selected portions of the UV curable material that have been cured can remain adhered to the housing surface.
Consequently, the product marking process 100 serves to mark the housing surface of the product through use of selected portions of the UV curable material. The markings provided by the product marking process 100 can be text and/or graphics. For example, a graphic provided by the marking might pertain to a logo, a certification mark or an approval mark. The markings can also be durable and have a high resolution.
Optionally, a protective coating can be applied on the outer surface of the housing portion 200 over the specific marking elements 204′ that have been formed in the layer of UV curable material 204. The protective coating can, for example, be translucent, such as clear acrylic.
The product marking process 300 can initially form 302 a physical mask layer having at least one predetermined opening. The predetermined opening is, for example, an opening that surrounds a region were text or graphics is to be applied to the outer housing surface. In other words, the predetermined opening is oversized as compared to the region where text or graphic is to be applied on the outer housing surface. In one implementation, the physical mask layer can, for example, be implemented by a film having at die cut for the predetermined opening. In the event that the physical mask layer has more than one predetermined opening, the physical mask layer can have a die cut for each of the predetermined openings.
After the physical mask layer has been formed 302, the physical mask layer can be adhered 304 to the outer housing surface. In one implementation, the physical mask layer can be adhered 304 to the outer housing surface through use of an adhesive. For example, the physical mask can have an adhesive backing.
Next, a layer of UV curable material can be deposited 306 onto the outer housing surface. For example, a spray or printing technique can be used to deposit 306 a layer of UV curable material onto the outer housing surface. The layer of UV curable material being deposited 306 is the material that is to form the marking on the housing surface. For example, the layer of UV curable material can be a layer of UV curable adhesive, such as a curable coating DYMAX Multi-Cure 9-20557 available from DYMAX Corporation of Torrington, Conn. Thereafter, the physical mask layer can be removed 308 from the outer housing surface.
After the physical mask layer has been removed 308, the product marking process 300 can UV cure 310 that portion of the layer of UV curable material that is desired to form the marking. The UV cure 310 can utilize a laser to precisely cure portions of the layer of UV curable material that has been deposited 306 onto the outer housing surface. The UV cure 310 can thus form specific graphical elements and/or text elements from the layer of UV curable material by UV cure 310 of those portions of the layer of material that are used to represent the desired graphical elements and/or textual elements that are to remain on the outer housing surface. In one implementation, the laser performing the UV cure 310 is a marking laser that produces ultra-violent light (e.g., 355 nanometer (NM) laser). Although various different lasers can be used, one supplier for making lasers is TRUMPF Inc. of Farmington, Conn. Through proper control of the laser, the UV cure 310 of desired portions of the layer of UV curable material can be selectively performed without damage to the surface of the outer surface housing.
After the UV cure 310 has been performed, those remaining portions of the layer of UV curable material that are uncured can be removed 312 from the outer housing surface. Hence, the portions of the layer of UV curable material that have been UV cured remain adhered to the outer housing surface, while those other portions that have not been UV cured are removed. A fluid can be use to rinse off the remaining portions of the layer of UV curable material that are uncured. The fluid can, for example, be water and/or a dissolvent (e.g., isopropyl alcohol).
Subsequently, a translucent protective layer can be applied 314 to the outer housing surface. Although the translucent protective layer is not required, the translucent protective layer can serve to protect the portion of the layer of UV curable material that is used to represent the one or more desired graphical elements and/or textual elements on the outer housing surface. For example, the translucent protective layer can be a layer of acrylic. After the translucent protective layer has been applied 314, the product marking process 300 can end.
It should be noted that the use of a physical mask in the product marking process 300 is optional. The physical mask serves to confine the area(s) where the layer of UV curable material is provided. Hence, in one embodiment, the product marking can be performed with simply operations 306, 310 and 312 of the product marking process 300.
Although embodiment discussed above can operate to selectively curing UV curable material using a laser providing UV light, it should be noted that UV light for curing can be provided by other UV light sources. Additionally, in some embodiments, deposited UV curable material can be cured using multiple different UV light sources. For example, a wide UV light source (e.g., flood light) can be used to cure a large area, while for small marking features a narrow UV light source (e.g., UV laser) can be used.
Although UV curing is primarily discussed above, other curing can be performing. For example, infrared (IR) light can be used to cure an IR curable material in much the same manner that an IT curable material is cured by UV light. IR curing uses heat generated by IR light to cure the IR curing material. An IR laser can produce the IR light. Through process control (e.g., pulse-width, intensity, etc.), the amount of IR light being deposed can be controlled. Further, in one embodiment, curing can be provided by a combination of UV curing and IR curing. For example, a laser source could output either or both of UV light and IR light. With both UV and IR light sources, the curing may be efficiently performed by controlling not only UV light but also IR light so that the curing material can be heated as appropriate while being US cured.
In some embodiments it may be desirable to use ablation to at least partially form the product marking. For example, in one embodiment, at least a portion of the cured UV curable material that has been cured on a product surface can be further ablated (e.g., using a laser). The ablation can, for example, be used to assist in forming detailed and precise text and/or graphics for the product marketing. Additional details on using ablation for forming product marking are provided in U.S. Provisional Patent Application No. 61/121,491 which is incorporated herein by reference below.
In another embodiment, a material (e.g., UV ink) can be configured to be specifically sensitive to UV radiation. In one example, the material can be sensitive to the UV radiation such that the material can be partially cured. Then, after being partially cured, the material that has not been partially cured can be cleaned from the surface. Subsequently, the remaining partially-cured material can be completely cured.
Initially, the product marking process 600 deposits 602 a layer of ultra-violet (UV) curable material onto a housing surface of a product. In one embodiment, the UV curable material can be adhesive material that can be applied to the outer housing surface as an adhesive layer. The housing surface can be flat or curved.
Next, selected portions of the layer of UV curable material that are to remain on the housing surface can be partially cured 604. As a result, the selected portions of the UV curable material that are partially cured are not fully cured but are sufficiently cured to adhere to the housing surface. Here, in one implementation, UV light can be applied so as to partially cure the selected portions of the UV curable material. The UV light can be induced in a controlled manner, such as with a UV laser, to partially cure the selected portions of the UV curable material.
The remaining portions of the layer of UV curable material that have not been partially cured can be removed 606 from the housing surface. Since the remaining portions (i.e., unselected portions) of the UV curable material have not been cured, such remaining have not been cured enough to significantly adhere to the housing surface. As a result, through use of a fluid (e.g., water, solution, dissolvent), the remaining portions of the UV curable material can be removed from the housing surface, while the selected portions of the UV curable material that have been partially cured are able to remain adhered to the housing surface.
Thereafter, the selected portions of the layer of UV curable material that were previously partially cured and that are to remain on the housing surface can be completely cured 608. As a result, the selected portions of the UV curable material that were previously partially cured are now fully cured and firmly adhered to the housing surface. Here, in one implementation, UV light can be applied so as to complete the curing of the selected portions of the UV curable material. The UV light can be induced in a bulk manner, such as with a UV lamp, to complete the curing of the selected portions, i.e., the remaining portions, of the UV curable material.
Consequently, the product marking process 600 serves to mark the housing surface of the product through use of selected portions of the UV curable material. The markings provided by the product marking process 600 can be text and/or graphics. For example, a graphic provided by the marking might pertain to a logo, a certification mark or an approval mark. The markings can also be durable and have a high resolution.
Optionally, a protective coating can be applied on the outer surface of the housing portion 700 over the completely cured specific marking elements 704″ that have been formed in the layer of UV curable material 704. The protective coating can, for example, be translucent, such as clear acrylic.
In another embodiment, a marking material, such as UV ink, can be configured to be specifically sensitive to multiple different wavelengths of UV radiation. In one example, the marking material can be configured to be sensitive to radiation, such as UV radiation, of a first wavelength and a second wavelength. For example, in a first pass, a UV laser applying UV radiation of a first wavelength can be used to cure selective portions of the marking material, and then, in a second pass, a laser can apply radiation to ablate away undesired portions of the marking material.
Initially, the product marking process 800 deposits 802 a layer of ultra-violet (UV) curable material onto a housing surface of a product. In one embodiment, the UV curable material can be adhesive material that can be applied to the housing surface. The housing surface can be flat or curved.
Next, selected portions of the UV curable material can be selectively cured 804 using UV radiation of a first wavelength. The selected portions of the UV curable material that are those portions of the UV curable material that are to remain on the housing surface. The UV curable material can be configured to be sensitive to radiation, such as UV radiation, of the first wavelength. As an example, the UV radiation for curing can be applied by a UV laser which selectively provides controlled UV radiation of the first wavelength. Hence, the selective application of radiation causes the selected portion of the UV curable material to be cured and thus become firmly adhered to the housing surface.
Thereafter, unselected portions of the layer of UV curable material (i.e., those portions that have not been cured) can be removed 806 from the housing surface using UV radiation of a second wavelength. For example, the selective application of UV radiation of the second wavelength can cause the unselected portions of the UV curable material to be ablated away from the housing surface. As an example, the UV radiation for ablation can be applied by a UV laser which selectively provides controlled UV radiation of the second wavelength.
Consequently, the product marking process 800 serves to mark the housing surface of the product through use of selected portions of the UV curable material. The markings provided by the product marking process 800 can be text and/or graphics. For example, a graphic provided by the marking might pertain to a logo, a certification mark or an approval mark. The markings can also be durable and have a high resolution.
The product marking process shown in
Optionally, the product marking process 800 can have a protective coating applied on the outer surface of the housing portion 200 over the specific marking elements 204′ that have been formed in the layer of UV curable material 204. The protective coating can, for example, be translucent, such as clear acrylic.
In still another embodiment, a marking material can be placed on a surface and configured to selected change color under laser control. The marking material, such as ink, can include one or more initiators. For example, the initiators can be dye additives (e.g., micro dye capsules embedded in the marking material. The one or more initiators in the marking material can serve as color activators. Laser energy can then be selectively applied to initiate colorization of the marking material (e.g., by activating, breaking or bursting the micro dye capsules). Different initiators can be receptive to different wavelength of laser energy such that different colors can be produced using different wavelengths. The colorization can be induced before, during or after cure of the marking material.
According to the color marking process 900, a first predetermined wavelength of radiation can be applied 902 to desired portions of curable material that are to be colored by a first color. These desired portions are also portions of the curable material that are to remain on the housing surface. The curable material, such as UV curable material, can be configured to include color activators of the first color that are sensitive to radiation, such as UV radiation, of the first predetermined wavelength. As an example, the UV radiation for activating the first color can be applied by a UV laser which selectively provides controlled UV radiation of the first predetermined wavelength that serves to activate the first color (e.g., by breaking or bursting micro dye capsules or otherwise releasing dye from the micro dye capsules). Hence, the controlled application of radiation of the first predetermined wavelength causes color initiators in the curable material to be activated to release color so as to colorize the desired portions with the first color.
In addition, a second predetermined wavelength of radiation can be applied 904 to desired portions of curable material that are to be colored by a second color. These desired portions are also portions of the curable material that are to remain on the housing surface. The curable material, such as UV curable material, can be configured to include color activators of the second color that are sensitive to radiation, such as UV radiation, of the second predetermined wavelength. As an example, the UV radiation for activating the second color can be applied by a UV laser which selectively provides controlled UV radiation of the second predetermined wavelength that serves to activate the second color (e.g., by breaking or bursting micro dye capsules or otherwise releasing dye from the micro dye capsules). Hence, the controlled application of radiation of the second predetermined wavelength causes color initiators in the curable material to be activated to release color so as to colorize the desired portions with the second color.
Optionally, the curable material can be configured to include color activators of one or more additional colors that are sensitive to radiation, such as UV radiation, of additional predetermined wavelengths. The controlled application of radiation of the additional predetermined wavelengths can cause various color initiators in the curable material to be activated to release color so as to colorize the desired portions with the additional color. It should be noted that two or more colors can be mixed if activated at the same region in the curable material.
In one embodiment, the product marking techniques discussed herein can be used to provide markings on a portable electronic device. The portable electronic device can further be a handheld electronic device. The term handheld generally means that the electronic device has a form factor that is small enough to be comfortably held in one hand. Typically, a handheld electronic device is less than one (1) pound in weight. A hand-held electronic device may be directed at one-handed operation or two-handed operation. In one-handed operation, a single hand is used to both support the device as well as to perform operations with the user interface during use. In two-handed operation, one hand is used to support the device while the other hand performs operations with a user interface during use or alternatively both hands support the device as well as perform operations during use. In some cases, the hand-held electronic device is sized for placement into a pocket of the user. By being pocket-sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels (e.g., the user is not limited by carrying a large, bulky and often heavy device).
